Abstract

A contactless charging device is disclosed having a power connector, a cable, and a charging head. The cable has a first end connected to the power connector. The charging head is connected to an opposite second end of the cable, and has a magnet or a magnetic substance, and an electromagnetic coil.

Claims

1. A contactless charging device comprising:

a power connector;

a cable having a first end connected to the power connector; and

a charging head connected to an opposite second end of the cable, and having a magnet or a magnetic substance, and

an electromagnetic coil.

2. The contactless charging device of claim 1, wherein the magnet or a magnetic substance magnetically attracted to a mobile terminal having a corresponding magnetic substance or magnet.

3. The contactless charging device of claim 2, wherein the electromagnetic coil is in contactless electrical communication with the mobile terminal.

4. The contactless charging device of claim 3, wherein the charging head contacts a connecting surface of the mobile terminal.

5. The contactless charging device of claim 3, wherein the charging head contacts a region of the mobile terminal that includes a portion of the connecting surface.

6. The contactless charging device of claim 2, wherein the charging head is magnetically attracted to a connecting surface of the mobile terminal.

7. The contactless charging device of claim 2, wherein the charging head wirelessly supplies electrical power to the mobile terminal through the connecting surface.

8. The contactless charging device of claim 2, wherein the mobile terminal has a display screen on a first surface.

9. The contactless charging device of claim 8, wherein the charging head further includes a coil supporting member.

10. The contactless charging device of claim 9, wherein the electromagnetic coil is positioned in the coil supporting member.

11. The contactless charging device of claim 9, wherein the coil supporting member contacts a second surface of the mobile terminal opposite to the first surface.

12. The contactless charging device of claim 10, wherein the electromagnetic coil wirelessly supplies the electrical power to the mobile terminal through the second surface.

13. The contactless charging device of claim 9, wherein the coil supporting member further comprises a sleeve having a charging head receiving space.

14. The contactless charging device of claim 13, wherein the charging head is positioned in the charging head receiving space.

15. The contactless charging device of claim 13, wherein the coil supporting member extends outward from the sleeve and has a plate-like or tab-like shape.

16. The contactless charging device of claim 1, wherein the power connector and the cable transmit electrical power.

17. The contactless charging device of claim 16, wherein the power connector and the cable additionally transmit data.

18. The contactless charging device of claim 17, wherein the charging head further includes a communication module.

19. The contactless charging device of claim 18, wherein the communication module is in wireless communication with a mobile terminal.
